Mechanized Harvesting Systems in Permanent Stands and Technology
The application of different modern logging systems depends on the silvicultural aims and methodologies. Depending upon these specifications the appropriate technique must be selected. This is the basic condition, which leads to a specific logging system in Central European and especially in German forestry. In the following an overview is to be given upon the different applications of full-mec...

متن کاملHarvesting Energy from CO2 Emissions
When two fluids with different compositions are mixed, mixing energy is released. This holds true for both liquids and gases, though in the case of gases, no technology is yet available to harvest this energy source. Mixing the CO2 in combustion gases with air represents a source of energy with a total annual worldwide capacity of 1570 TWh. To harvest the mixing energy from CO2-containing gas e...
متن کاملWorldwide Development of Wind Energy and CO2 Emission Reduction
One of the most considerable issues in the global society is reducing CO2 emissions of industrial activities and its consequences. Therefore, exploitation of clean energy sources is one of the requirements of the international community. In this regard, the researchers investigated the impact of renewable energy utilization to achieve the low carbon economy and concluded that it can significant...
